Color black vs. Color transparent

Hi, there.

In Color class >> colorFromPixelValue:depth: we have:

...
d = 32 ifTrue: [
                "eight bits per component; 8 bits of alpha"
                r := (p bitShift: -16) bitAnd: 16rFF.
                g := (p bitShift: -8) bitAnd: 16rFF.
                b := p bitAnd: 16rFF.
                alpha := p bitShift: -24.
                alpha = 0 ifTrue: [^Color transparent].
                (r = 0 and: [g = 0 and: [b = 0]])  ifTrue: [^Color transparent].
                alpha < 255
                        ifTrue: [^ (Color r: r g: g b: b range: 255) alpha: (alpha asFloat / 255.0)]
                        ifFalse: [^ (Color r: r g: g b: b range: 255)]].
...

This denotes black to transparent. Is this still right?

I have here a form that renders right but after collecting the colors, all is transparent:

 '(Form

        offset: 0@0)'

And after "form collectColors: [:ea | ea]" if get this:

 '(Form
        extent: 16@16
        depth: 32
        fromArray: #( 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0)
